Description

technical field [0001] The invention relates to a household electronic scale, in particular to a household electronic scale with voice reporting and digital display. Background technique [0002] An electronic scale is a kind of weighing instrument, which is a tool to measure the mass of an object by using Hooke's law or the principle of lever balance of force; , sensors) and display systems (such as dials, electronic display instruments) are composed of three parts. According to the structural principle, they can be divided into three categories: mechanical scales, electronic scales, and electromechanical combination scales. [0003] The electronic scale adopts the electronic weighing device integrated with modern sensor technology, electronic technology and computer technology to meet and solve the "fast, accurate, continuous and automatic" weighing requirements in real life, and at the same time effectively eliminate human errors. It is more in line with the application ...
